 Phase 7 (TBD) - Sharing of variables between threads (ideally without limitation, but that might not be realistic)
 
 TODO:
-
-- multiple mutators, and threading functions/types.  probably want this on a new branch, when ready
-  part of this is implementing the beginnings of srfi-18, to create multiple threads, sync them, etc
-  next steps:
-
-  - need a different set of exception handlers for each stack. 
-    Probably need to move *exception-handler-stack* from being a global
-    to being part of thread data
-    Will need to branch for this since there are going to be changes 
-    throughout many files... the actual change may not be so bad though,
-    and may simplify the code, which is kind of hacky right now.
-  - start making core stuff thread safe. for example, test.scm sometimes
-    crashes, I think printing out result from (read)
-  - assume I/O and eval both have threading issues
-
 - bring exceptions into local thread data? anything else?
   also, will probably need to lock shared resources such as I/O...
   Yes, anything global needs to be considered.

       what is the performance impact of adding locks to all these funcs?

   mostly what minor/major GC's are, and how they are interleaved.
